In this paper we show how the string landscape can be constrained using observational data. We illustrate this idea by focusing on fiber inflation which is a promising class of string inflationary models in type IIB flux compactifications. We determine the values of the microscopic flux-dependent parameters which yield the best fit to the most recent cosmological datasets.

Abstract
In this paper we show how the string landscape can be constrained using observational data. We illustrate this idea by focusing on fiber inflation which is a promising class of string inflationary models in type IIB flux compactifications. We determine the values of the microscopic flux-dependent parameters which yield the best fit to the most recent cosmological datasets.File in questo prodotto:
